Devices and Methods for Controlling Media Presentation

ABSTRACT

An electronic device is configured to: while presenting media content at a first non-zero playback speed, detect a press input by a first contact on a first media control; and, in response to detecting the press input: determine whether an intensity of the first contact is above a first intensity threshold; if the intensity of the first contact is above the first intensity threshold, present the media content at a second playback speed, where the second playback speed is faster than the first non-zero playback speed; and, if the intensity of the first contact is below the first intensity threshold, maintain presentation of the media content at the first non-zero playback speed.

RELATED APPLICATION

This application is a continuation of U.S. application Ser. No. 14/866,159, filed Sep. 25, 2015, which claims priority to U.S. Provisional Patent Application Ser. No. 62/129,941, filed Mar. 8, 2015, entitled “Devices and Methods for Controlling Media Presentation,” both of which are incorporated by reference herein in their entirety.

TECHNICAL FIELD

This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces for controlling playback of digital media, including fast scanning through media files.

BACKGROUND

The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touchpads and touch-screen displays. Such surfaces are sometimes used to control presentation of video, audio, and/or other media on a display, for example by interacting with virtual play, pause, fast forward, and rewind buttons on the display.

But existing methods and devices for controlling media presentation are cumbersome and inefficient. For example, the inputs required to adjust playback speed may not be clear and intuitive to a user.

SUMMARY

Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for controlling media presentation (e.g., controlling the rewind, fast forward, and/or playback speeds of various media). Such methods and interfaces optionally complement or replace conventional methods for controlling media presentation. Such methods and interfaces reduce the number, extent, and/or nature of the inputs from a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges.

The above deficiencies and other problems associated with user interfaces for electronic devices with touch-sensitive surfaces are reduced or eliminated by the disclosed devices. In some embodiments, the device is a desktop computer. In some embodiments, the device is portable (e.g., a notebook computer, tablet computer, or handheld device). In some embodiments, the device is a personal electronic device (e.g., a wearable electronic device, such as a watch). In some embodiments, the device has a touchpad. In some embodiments, the device has a touch-sensitive display (also known as a “touch screen” or “touch-screen display”). In some embodiments, the device has a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through stylus and/or finger contacts and gestures on the touch-sensitive surface. In some embodiments, the functions optionally include image editing, drawing, presenting, word processing, spreadsheet making, game playing, telephoning, video conferencing, e-mailing, instant messaging, workout support, digital photographing, digital videoing, web browsing, digital music playing, note taking, and/or digital video playing. Executable instructions for performing these functions are, optionally, included in a non-transitory computer readable storage medium or other computer program product configured for execution by one or more processors.

In accordance with some embodiments, a method is performed at an electronic device with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. The method includes: while presenting media content at a first non-zero playback speed, detecting a press input by a first contact on the touch-sensitive surface that corresponds to a focus selector at a first location of a first media control on the display; and, in response to detecting the press input: determining whether an intensity of the first contact is above a first intensity threshold; in accordance with a determination that the intensity of the first contact is above the first intensity threshold, presenting the media content at a second playback speed, wherein the second playback speed is faster than the first non-zero playback speed; and, in accordance with a determination that the intensity of the first contact is below the first intensity threshold, maintaining presentation of the media content at the first non-zero playback speed.

In accordance with some embodiments, a method is performed at an electronic device with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface.

DESCRIPTION OF EMBODIMENTS

Many electronic devices provide a media playback function for presenting media content (e.g., music, video, a collection of images in a slideshow, etc.). A software application that provides the media playback function typically provides respective graphical user interface controls for controlling various aspects of media presentation (e.g., for starting, pausing, stopping, fast forwarding, and/or rewinding the media content). Sometimes, the user may wish to start playing the media content at a speed higher than the normal playback speed (e.g., scanning the media content at 2×, 5×, 10×). Sometimes, while playing the media content at a normal playback speed (e.g., 1×), the user may wish to increase the playback speed to multiple times of the normal playback speed (e.g., scanning at 2×, 5×, 10×, 30×, etc.). Sometimes, while the media content is being scanned at a first speed (e.g., 2×), the user may wish to change that speed to a higher speed (e.g., 5×, 10×, 30×, etc.). Sometimes, the user may wish to increase the speed for just a brief time; while at other times, the user may wish to maintain the higher playback speed once it has been achieved.

Here improved methods are described for controlling media presentation based on an intensity of a press input or a profile of the intensity of the press input on a touch-sensitive surface of the electronic device. Depending on a current playback speed of the media presentation and a relative intensity of a press input to one or more predetermined activation intensity thresholds associated with different playback speeds, the playback speed of the media presentation may be altered. For example, the playback speed may increase or decrease in response to changes in contact intensity of the press input detected on a corresponding user interface control (e.g., a fast forward control or a rewind control). These methods provide more convenient and intuitive ways to control media presentation, thereby reducing the cognitive burden on a user and increasing the effectiveness, efficiency, and user satisfaction with such devices.

Below, FIGS. 1A-1B, 2, and 3 provide a description of exemplary devices. FIGS. 4A-4B and 5A-5F illustrate exemplary user interfaces for controlling media presentation. FIGS. 6A-6K illustrate exemplary control heuristics for controlling media presentation. FIGS. 7A-7H and 8A-8C are flow diagrams of methods of controlling media presentation. The user interfaces in FIGS. 5A-5F and the control heuristics in FIGS. 6A-6K are used to illustrate the processes in FIGS. 7A-7H and 8A-8C.

Exemplary Devices

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

It will also be understood that, although the terms first, second, etc. are, in some instances, used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described embodiments. The first contact and the second contact are both contacts, but they are not the same contact, unless the context clearly indicates otherwise.

The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch-screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch-screen display and/or a touchpad).

In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick.

The device typically supports a variety of applications, such as one or more of the following: a note taking application, a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices with touch-sensitive displays. FIG. 1A is a block diagram illustrating portable multifunction device 100 with touch-sensitive display system 112 in accordance with some embodiments. Touch-sensitive display system 112 is sometimes called a “touch screen” for convenience, and is sometimes simply called a touch-sensitive display. Device 100 includes memory 102 (which optionally includes one or more computer readable storage mediums), memory controller 122, one or more processing units (CPUs) 120, peripherals interface 118, RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem 106, other input or control devices 116, and external port 124. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more intensity sensors 165 for detecting intensity of contacts on device 100 (e.g., a touch-sensitive surface such as touch-sensitive display system 112 of device 100). Device 100 optionally includes one or more tactile output generators 167 for generating tactile outputs on device 100 (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system 112 of device 100 or touchpad 355 of device 300). These components optionally communicate over one or more communication buses or signal lines 103.

As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 1A are implemented in hardware, software, firmware, or a combination thereof, including one or more signal processing and/or application specific integrated circuits.

Memory 102 optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 102 by other components of device 100, such as CPU(s) 120 and the peripherals interface 118, is, optionally, controlled by memory controller 122.

Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU(s) 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data.

In some embodiments, peripherals interface 118, CPU(s) 120, and memory controller 122 are, optionally, implemented on a single chip, such as chip 104. In some other embodiments, they are, optionally, implemented on separate chips.

RF (radio frequency) circuitry 108 receives and sends RF signals, also called electromagnetic signals. RF circuitry 108 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry 108 optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry 108 optionally communicates with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The wireless communication optionally uses any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSDPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11ac, IEEE 802.11ax, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data is, optionally, retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, FIG. 2). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 106 couples input/output peripherals on device 100, such as touch-sensitive display system 112 and other input or control devices 116, with peripherals interface 118. I/O subsystem 106 optionally includes display controller 156, optical sensor controller 158, intensity sensor controller 159, haptic feedback controller 161, and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input or control devices 116. The other input or control devices 116 optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 are, optionally, coupled with any (or none) of the following: a keyboard, infrared port, USB port, stylus, and/or a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) optionally include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons optionally include a push button (e.g., 206, FIG. 2).

Touch-sensitive display system 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch-sensitive display system 112. Touch-sensitive display system 112 displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output corresponds to user-interface objects.

Touch-sensitive display system 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch-sensitive display system 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch-sensitive display system 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch-sensitive display system 112. In an exemplary embodiment, a point of contact between touch-sensitive display system 112 and the user corresponds to a finger of the user or a stylus.

Touch-sensitive display system 112 optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch-sensitive display system 112 and display controller 156 optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch-sensitive display system 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch-sensitive display system 112 optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen video resolution is in excess of 400 dpi (e.g., 500 dpi, 800 dpi, or greater). The user optionally makes contact with touch-sensitive display system 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch-sensitive display system 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 optionally also includes one or more optical sensors 164. FIG. 1A shows an optical sensor coupled with optical sensor controller 158 in I/O subsystem 106. Optical sensor(s) 164 optionally include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor(s) 164 receive light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor(s) 164 optionally capture still images and/or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch-sensitive display system 112 on the front of the device, so that the touch screen is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image is obtained (e.g., for selfies, for videoconferencing while the user views the other video conference participants on the touch screen, etc.).

Device 100 optionally also includes one or more contact intensity sensors 165. FIG. 1A shows a contact intensity sensor coupled with intensity sensor controller 159 in I/O subsystem 106. Contact intensity sensor(s) 165 optionally include one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor(s) 165 receive contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112). In some embodiments, at least one contact intensity sensor is located on the back of device 100, opposite touch-screen display system 112 which is located on the front of device 100.

Device 100 optionally also includes one or more proximity sensors 166. FIG. 1A shows proximity sensor 166 coupled with peripherals interface 118. Alternately, proximity sensor 166 is coupled with input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch-sensitive display system 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 optionally also includes one or more tactile output generators 167. FIG. 1A shows a tactile output generator coupled with haptic feedback controller 161 in I/O subsystem 106. Tactile output generator(s) 167 optionally include one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Tactile output generator(s) 167 receive tactile feedback generation instructions from haptic feedback module 133 and generates tactile outputs on device 100 that are capable of being sensed by a user of device 100. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 100) or laterally (e.g., back and forth in the same plane as a surface of device 100). In some embodiments, at least one tactile output generator sensor is located on the back of device 100, opposite touch-sensitive display system 112, which is located on the front of device 100.

Device 100 optionally also includes one or more accelerometers 168. FIG. 1A shows accelerometer 168 coupled with peripherals interface 118.

In some embodiments, information is displayed on the touch-screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, haptic feedback module (or set of instructions) 133, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments, memory 102 stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch-sensitive display system 112; sensor state, including information obtained from the device's various sensors and other input or control devices 116; and location and/or positional information concerning the device's location and/or attitude.

Operating system 126 (e.g., iOS, Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. In some embodiments, the external port is a Lightning connector that is the same as, or similar to and/or compatible with the Lightning connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif.

Contact/motion module 130 optionally detects contact with touch-sensitive display system 112 (in conjunction with display controller 156) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact (e.g., by a finger or by a stylus), such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts or stylus contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

Contact/motion module 130 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event. Similarly, tap, swipe, drag, and other gestures are optionally detected for a stylus by detecting a particular contact pattern for the stylus.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch-sensitive display system 112 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast or other visual property) of graphics that are displayed.

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 102 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 102 optionally stores additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 is, optionally, reduced.

The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that is displayed on device 100. In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (in FIGS. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 136, 137-155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch-sensitive display system 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display system 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display system 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripheral interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views, when touch-sensitive display system 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver module 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 optionally utilizes or calls data updater 176, object updater 177 or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 includes one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170, and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which optionally include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event 187 include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display system 112, and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display system 112, when a touch is detected on touch-sensitive display system 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event 187 also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module 145. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input-devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen (e.g., touch-sensitive display system 112, FIG. 1A) in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 optionally also includes one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 is, optionally, used to navigate to any application 136 in a set of applications that are, optionally executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on the touch-screen display.

In some embodiments, device 100 includes the touch-screen display, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, Subscriber Identity Module (SIM) card slot 210, head set jack 212, and docking/charging external port 124. Push button 206 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In some embodiments, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 113. Device 100 also, optionally, includes one or more contact intensity sensors 165 for detecting intensity of contacts on touch-sensitive display system 112 and/or one or more tactile output generators 167 for generating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPU's) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch-screen display. I/O interface 330 also optionally includes a keyboard and/or mouse (or other pointing device) 350 and touchpad 355, tactile output generator 357 for generating tactile outputs on device 300 (e.g., similar to tactile output generator(s) 167 described above with reference to FIG. 1A), sensors 359 (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s) 165 described above with reference to FIG. 1A). Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 optionally includes one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1A), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1A) optionally does not store these modules.

Each of the above identified elements in FIG. 3 are, optionally, stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 370 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 370 optionally stores additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces (“UI”) that are, optionally, implemented on portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),         such as cellular and Wi-Fi signals;     -   Time 404;     -   Bluetooth indicator 405;     -   Battery status indicator 406;     -   Tray 408 with icons for frequently used applications, such as:         -   Icon 416 for telephone module 138, labeled “Phone,” which             optionally includes an indicator 414 of the number of missed             calls or voicemail messages;         -   Icon 418 for e-mail client module 140, labeled “Mail,” which             optionally includes an indicator 410 of the number of unread             e-mails;         -   Icon 420 for browser module 147, labeled “Browser;” and         -   Icon 422 for video and music player module 152, also             referred to as iPod (trademark of Apple Inc.) module 152,             labeled “iPod;” and     -   Icons for other applications, such as:         -   Icon 424 for IM module 141, labeled “Messages;”         -   Icon 426 for calendar module 148, labeled “Calendar;”         -   Icon 428 for image management module 144, labeled “Photos;”         -   Icon 430 for camera module 143, labeled “Camera;”         -   Icon 432 for online video module 155, labeled “Online             Video;”         -   Icon 434 for stocks widget 149-2, labeled “Stocks;”         -   Icon 436 for map module 154, labeled “Maps;”         -   Icon 438 for weather widget 149-1, labeled “Weather;”         -   Icon 440 for alarm clock widget 149-4, labeled “Clock;”         -   Icon 442 for workout support module 142, labeled “Workout             Support;”         -   Icon 444 for notes module 153, labeled “Notes;” and         -   Icon 446 for a settings application or module, which             provides access to settings for device 100 and its various             applications 136.

It should be noted that the icon labels illustrated in FIG. 4A are merely exemplary. For example, in some embodiments, icon 422 for video and music player module 152 is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 450. Device 300 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 357) for detecting intensity of contacts on touch-sensitive surface 451 and/or one or more tactile output generators 359 for generating tactile outputs for a user of device 300.

FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 450. Although many of the examples that follow will be given with reference to inputs on touch screen display 112 (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 4B. In some embodiments, the touch-sensitive surface (e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures, etc.), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or a stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector,” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 451 in FIG. 4B) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch-screen display (e.g., touch-sensitive display system 112 in FIG. 1A or the touch screen in FIG. 4A) that enables direct interaction with user interface elements on the touch-screen display, a detected contact on the touch-screen acts as a “focus selector,” so that when an input (e.g., a press input by the contact) is detected on the touch-screen display at a location of a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch-screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch-screen display) that is controlled by the user so as to communicate the user's intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device).

As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact or a stylus contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average or a sum) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be readily accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button).

In some embodiments, contact/motion module 130 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation intensity thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 100). For example, a mouse “click” threshold of a trackpad or touch-screen display can be set to any of a large range of predefined thresholds values without changing the trackpad or touch-screen display hardware. Additionally, in some embodiments, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter).

As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds may include a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second intensity threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more intensity thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective option or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation.

In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface may receive a continuous swipe contact transitioning from a start location and reaching an end location (e.g., a drag gesture), at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location may be based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm may be applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity.

The control heuristics figures (e.g., FIGS. 6A-6K) described below include various intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to one or more intensity thresholds (e.g., a light press activation intensity threshold I_(LA), respective activation intensity threshold IT_(speedA) associated with various playback speeds, a light press release intensity threshold I_(LR) and/or respective release intensity thresholds associated with various playback speeds). In some embodiments, the light press activation intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the higher activation intensity thresholds correspond to intensities at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press activation intensity threshold or the higher activation intensity thresholds. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures.

In some embodiments, the response of the device to inputs detected by the device depends on criteria based on the contact intensity during the input. For example, for some “light press” inputs, the intensity of a contact exceeding a first intensity threshold during the input triggers a first response. In some embodiments, the response of the device to inputs detected by the device depends on criteria that include both the contact intensity during the input and time-based criteria. For example, for some “deep press” inputs (e.g., press inputs with intensities reaching above one or more of the higher activation intensity thresholds), the intensity of a contact exceeding a second intensity threshold during the input, greater than the first intensity threshold for a light press, triggers a second response only if a delay time has elapsed between meeting the first intensity threshold and meeting the second intensity threshold. This delay time is typically less than 200 ms in duration (e.g., 40, 100, or 120 ms, depending on the magnitude of the second intensity threshold, with the delay time increasing as the second intensity threshold increases). This delay time helps to avoid accidental deep press inputs. As another example, for some “deep press” inputs, there is a reduced-sensitivity time period that occurs after the time at which the first intensity threshold is met. During the reduced-sensitivity time period, the second intensity threshold is increased. This temporary increase in the second intensity threshold also helps to avoid accidental deep press inputs. For other deep press inputs, the response to detection of a deep press input does not depend on time-based criteria.

In some embodiments, one or more of the input intensity thresholds and/or the corresponding outputs vary based on one or more factors, such as user settings, contact motion, input timing, application running, rate at which the intensity is applied, number of concurrent inputs, user history, environmental factors (e.g., ambient noise), focus selector position, and the like. Exemplary factors are described in U.S. patent application Ser. Nos. 14/399,606 and 14/624,296, which are incorporated by reference herein in their entireties.

For example, FIG. 4C illustrates a dynamic intensity threshold 480 that changes over time based in part on the intensity of touch input 476 over time. Dynamic intensity threshold 480 is a sum of two components, first component 474 that decays over time after a predefined delay time pl from when touch input 476 is initially detected, and second component 478 that trails the intensity of touch input 476 over time. The initial high intensity threshold of first component 474 reduces accidental triggering of a “deep press” response, while still allowing an immediate “deep press” response if touch input 476 provides sufficient intensity. Second component 478 reduces unintentional triggering of a “deep press” response by gradual intensity fluctuations of a touch input. In some embodiments, when touch input 476 satisfies dynamic intensity threshold 480 (e.g., at point 481 in FIG. 4C), the “deep press” response is triggered.

FIG. 4D illustrates another dynamic intensity threshold 486 (e.g., intensity threshold I_(D)). FIG. 4D also illustrates two other intensity thresholds: a first intensity threshold I_(H) and a second intensity threshold I_(L). In FIG. 4D, although touch input 484 satisfies the first intensity threshold I_(H) and the second intensity threshold I_(L) prior to time p2, no response is provided until delay time p2 has elapsed at time 482. Also in FIG. 4D, dynamic intensity threshold 486 decays over time, with the decay starting at time 488 after a predefined delay time p1 has elapsed from time 482 (when the response associated with the second intensity threshold I_(L) was triggered). This type of dynamic intensity threshold reduces accidental triggering of a response associated with the dynamic intensity threshold I_(D) immediately after, or concurrently with, triggering a response associated with a lower intensity threshold, such as the first intensity threshold I_(H) or the second intensity threshold I_(L).

FIG. 4E illustrate yet another dynamic intensity threshold 492 (e.g., intensity threshold I_(D)). In FIG. 4E, a response associated with the intensity threshold I_(L) is triggered after the delay time p2 has elapsed from when touch input 490 is initially detected. Concurrently, dynamic intensity threshold 492 decays after the predefined delay time p1 has elapsed from when touch input 490 is initially detected. So a decrease in intensity of touch input 490 after triggering the response associated with the intensity threshold IL, followed by an increase in the intensity of touch input 490, without releasing touch input 490, can trigger a response associated with the intensity threshold I_(D) (e.g., at time 494) even when the intensity of touch input 490 is below another intensity threshold, for example, the intensity threshold I_(L).

An increase of characteristic intensity of the contact from an intensity below the light press activation intensity threshold IT_(LA) to an intensity between the light press activation intensity threshold IT_(LA) and the next higher activation intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below a higher activation intensity threshold to an intensity above the higher activation intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press activation intensity threshold IT_(LA) is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity is zero. In some embodiments, the contact-detection intensity is greater than zero. In some illustrations a shaded circle or oval is used to represent intensity of a contact on the touch-sensitive surface (e.g., as in shown by contact 512, FIGS. 5C-5E). In some illustrations, a circle or oval without shading is used represent a respective contact on the touch-sensitive surface without specifying the intensity of the respective contact.

In some embodiments, described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., the respective operation is performed on a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., the respective operation is performed on an “up stroke” of the respective press input).

In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., the respective operation is performed on an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).

For ease of explanation, the description of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. As described above, in some embodiments, the triggering of these responses also depends on time-based criteria being met (e.g., a delay time has elapsed between a first intensity threshold being met and a second intensity threshold being met).

User Interfaces and Associated Processes

Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device, such as portable multifunction device 100 or device 300, with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface.

FIGS. 5A-5F illustrate exemplary user interfaces for controlling media presentation in accordance with some embodiments. FIGS. 6A-6K illustrate exemplary control heuristics for controlling media presentation in accordance with some embodiments. The user interfaces and control heuristics in these figures are used to illustrate the processes described below, including the processes in FIGS. 7A-7H and 8A-8C. Although some of the examples which follow will be given with reference to inputs on a touch-screen display (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface 451 that is separate from the display 450, as shown in FIG. 4B.

FIG. 5A illustrates exemplary user interface 400 of an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) when a media player application (e.g., video and music player module represented by icon 422, FIG. 4A) is executed on the electronic device. The media player application provides a media playback function to present media content (e.g., a collection of images, animation, video, music, speech, etc.) continuously at a selected playback speed (e.g., 0×, 1×, 2×, 5×, 10×, 20×, 30×, 60×, etc.). Examples of the media player application includes a music player application, a video player application, a presentation application that displays a slideshow, a multi-media editor application, an audio recorder application, a photo editor application that displays photos in a slideshow, and the like. User Interface 400 includes content window 502 and various user interface controls for controlling different aspects of media presentation in the media player application. In some embodiments, content window 502 includes play button 504, and optionally a still image (e.g., an album cover image or representative video frame) or text (e.g., a title of media content) associated with a currently selected media file (e.g., a video clip titled “Life in the Desert”).

In some embodiments, user interface 400 further includes scrubber 506 which displays the total duration of the currently selected media content, and indicates (e.g., using indicator 508) the current playback progress of the selected media content. In some embodiments, a user can drag indicator 508 forward or backward along scrubber 506 to quickly jump to different locations in the selected media content.

In some embodiments, user interface 400 further includes a number of playback controls, including play control 510, fast forward control 512, and rewind control 514. Play control 510 is used to start normal playback (e.g., at 1× speed) of the media content. Fast forward control 512 is used to start fast forwarding of the media content, e.g., by playing the media content at a speed higher than the normal playback speed. Rewind control 512 is used start rewinding of the media content, e.g., by playing the media content backward at a speed higher than the normal playback speed. In some embodiments, as described later in the present disclosure, one or more of playback controls 510, 512 and 514 are used to increase the current playback speed to one or more higher levels. The higher playback speed may be momentary and lasts only for a user-specified duration (e.g., while the intensity of the press input meets certain criteria). Alternatively, the higher playback speeds may be maintained until a new input on one of the playback controls is received.

FIG. 5B illustrates that normal playback (e.g., at 1× speed) of the currently selected media content has been started, e.g., in response to a tap or light press input detected on play button 504 or play control 510. While the normal playback of the media content is ongoing, the current progress of the playback is indicated by indicator 508 on scrubber 506. In some embodiments, playback control 510 is replaced with pause control 518. In some embodiments, a stop control (not shown) may be included in user interface 400 for stopping the playback at any speed and return the start position of the selected media content to the beginning of the selected media content. For example, in some embodiments, a stop control may be presented next to playback controls 514, 518, or 512 after the media player has started playing the media content.

FIG. 5C illustrates that when a press input (e.g., represented by contact 520) is detected on fast forward control 512 while the media content is being presented at a normal playback speed (e.g., 1× speed), and the intensity of the contact reaches above a predetermined activation intensity threshold (e.g., the activation intensity threshold for a light press input I_(LA) or the activation intensity threshold associated with 2× speed), fast forward control 512 is optionally highlighted to indicate the activation of the fast forward function. In some embodiments, upon activation of the fast forward function, the speed by which the selected media content is presented in content window 502 is increased from the normal playback speed (e.g., 1× speed) to a first predetermined higher value (e.g., a first fast forward speed of two times the normal playback speed, or, 2× speed). In some embodiments, a playback speed indicator (e.g., speed indicator 522) is presented in user interface 400 to indicate the current playback speed (e.g., 2×). In some embodiments, tactile feedback (e.g., a tactile feedback that causes a click sensation in the user's finger in contact with fast forward control 512) is provided on touch screen 112 at the activation of the fast forward function.

FIG. 5D illustrates that when the intensity of the same press input (e.g., the press input represented by contact 520 in FIG. 5C) increases from the predetermined activation intensity threshold for 2× speed to a value above the next higher activation intensity threshold (e.g., the activation intensity threshold for 5× speed), the speed of the media playback is increased from the first fast forward speed (e.g., 2× speed) to a second, higher fast forward speed (e.g., 5× speed). In some embodiments, the higher fast forward speed (e.g., 5× speed) is indicated by speed indicator 522 in content window 502. In some embodiments, when the contact intensity reaches the second, higher activation intensity threshold (e.g., the activation intensity threshold for 5× speed), fast forward control 512 is highlighted (e.g., in a different manner from the highlighting shown in FIG. 5C) to indicate the activation of the second, higher fast forward speed. In some embodiments, tactile feedback (e.g., a tactile feedback that causes a click sensation in the user's finger in contact with fast forward control 512) is provided on touch screen 112 at the activation of the second, higher fast forward speed (e.g., 5× speed).

FIG. 5E illustrates that when the intensity of the same press input (e.g., the press input represented by contact 520 in FIGS. 5C and 5D) increases from the predetermined activation intensity threshold for 5× speed to above the next higher activation intensity threshold (e.g., the activation intensity threshold for 10× speed), the speed of the media playback is increased from the second fast forward speed (e.g., 5× speed) to a third, higher fast forward speed (e.g., 10× speed). In some embodiments, the higher fast forward speed (e.g., 10×) is indicated by speed indicator 522 in content window 502. In some embodiments, when the contact intensity reaches the next higher activation intensity threshold (e.g., the activation intensity threshold for 10× speed), fast forward control 512 is highlighted (e.g., in a different manner from the highlighting shown in FIGS. 5C and 5D) to indicate the activation of the higher fast forward speed (e.g., 10× speed). In some embodiments, tactile feedback (e.g., a tactile feedback that causes a click sensation in the user's finger in contact with fast forward control 512) is provided on touch screen 112 at the activation of the higher fast forward speed (e.g., 10× speed).

FIG. 5F illustrates that the press input (e.g., the press input represented by contact 520 in FIGS. 5C-5E) has been terminated (e.g., intensity of contact 520 has dropped below a predetermined release intensity threshold for a tap or light press input and/or become undetectable). Upon detection that the termination of press input, the playback speed of the media content is returned back to the normal playback speed (e.g., 1× speed). In some embodiments, when the playback speed is first returned to the normal playback speed, speed indicator 522 displays the playback speed (e.g., 1×). In some embodiments, after the playback speed has remained at the normal playback speed for a predetermined duration (e.g., 3 seconds), speed indicator 522 is optionally removed from content window 502. As shown in FIG. 5F, fast forward control 512 is returned to its normal un-highlighted appearance after the press input has been terminated.

In some embodiments, although not shown in FIGS. 5E and 5F, when the intensity of the press input drops gradually from a level above the activation intensity threshold for 10× speed to a level below the release intensity threshold for 2× speed, the intensity of contact 520 crosses respective release intensity thresholds for fast forward speed 10×, fast forward speed 5×, and fast forward speed 2×, one by one. In some embodiments, as the intensity of the contact crosses the respective release intensity thresholds of each of the fast forward speeds, the playback speed is dropped from a current fast forward speed to the next lower speed. Correspondingly, the highlighting of fast forward control 512 and the speed shown by speed indicator 522 are changed to those shown in FIGS. 5E, 5D, and 5C according to the current playback speed of the media content. In some embodiments, tactile feedback is provided at each instant that the respective release intensity threshold for the current fast forward speed is crossed.

The user interfaces illustrated in FIGS. 5A-5F are merely one example of how playback speed may be changed in response to a press input detected on a playback control. For example, in some embodiments, instead of a sustained press input, multiple press inputs or tap inputs may be used to raise the playback speed to different fast forward levels. In some embodiments, instead of returning the current playback speed to the normal playback speed or zero (0×) after a release intensity threshold for the lowest fast forward speed is crossed, the highest fast forward speed reached by a current press input can be locked in and maintained until a separate speed-restoring input is received (e.g., when a tap input is detected on pause control 518 or fast forward control 512). In some embodiments, whether to lock in a speed depends on the intensity profile of the press input relative to a predetermined lock time threshold (or time delay). In some embodiments, instead of increasing the playback speed in the forward direction in response to a press input detected on fast forward control 512, the rewind speed may be increased in a similar manner in response to a press input detected on rewind control 514.

FIGS. 6A-6K illustrate exemplary control heuristics for controlling media presentation in accordance with some embodiments. The control heuristics illustrated in these figures may be used in the processes described below, including the processes in FIGS. 7A-7H and 8A-8C. The inputs referenced in the description of the control heuristics may be inputs on a touch-screen display (where the touch-sensitive surface and the display are combined), or in some embodiments, inputs on a touch-sensitive surface 451 that is separate from the display 450, as shown in FIG. 4B.

FIGS. 6A and 6B illustrate how a lock time threshold T_(L) is used to determine whether a light press input that triggers activation of a first fast forward speed (e.g., 2×) will cause the fast forward speed to be locked in after the light press input is terminated. In FIGS. 6A and 6B, the initial playback speed at the time that the press input is received is zero (0×). In other words, the media content is in a paused or stopped state when the light press input is first detected (e.g., with a finger-down event triggered by the initial contact of a finger on the touch screen). The lock time threshold T_(L) may be any suitable length (e.g., 50 ms, 100 ms, 200 ms, 300 ms, 500 ms, 700 ms, or 1000 ms), and is optionally predefined in accordance with user preference or heuristics.

FIG. 6A illustrates an exemplary scenario where the intensity of the press input increases above the activation intensity threshold I_(2×A) (e.g., I_(2×A)=the activation intensity threshold I_(LA) for a “light press” input) of the first fast forward speed (e.g., 2×), and then falls below the release intensity threshold I_(2×R) (e.g., I_(2×R)=the release intensity threshold I_(LR) for a “light press” input) of the first fast forward speed (e.g., 2×) before the lock time threshold T_(L) expires. The intensity of the press input never reaches the activation intensity threshold of the next higher playback speed (e.g., I_(5×A)). As a result, the speed of playback is increased from zero (0×) to the first fast forward speed (e.g., 2×) upon crossing of the activation intensity threshold I_(2×A) and remains at the first fast forward speed (e.g., 2×) after the intensity of the press input drops below the release intensity threshold I_(2×R) for the first fast forward speed (e.g., 2×) and the press input is finally terminated (e.g., when the intensity drops below the contact-detection intensity or becomes undetectable).

FIG. 6B illustrates an exemplary scenario where, instead of falling below the release intensity threshold I_(2×R) before the lock time threshold T_(L) is reached, the intensity of the press input stayed above the release intensity threshold I_(2×R) until the lock time threshold T_(L) has expired. The intensity of the press input then falls below the release intensity threshold I_(2×R) of the first fast forward speed (e.g., 2×) before the press input is terminated. The intensity of the press input never reached the activation intensity of the next higher playback speed. As a result, the speed of playback is increased from zero (0×) to the first fast forward speed (e.g., 2×) upon crossing of the activation intensity threshold I_(2×A) and remains at the first fast forward speed (e.g., 2×) until the intensity of the press input drops below the release intensity threshold I_(2×R) for the first fast forward speed (e.g., 2×). In response to the intensity of the press input dropping below the release intensity threshold I_(2×R) for the first fast forward speed (e.g., 2×), the playback speed is decreased from the first fast forward speed (e.g., 2×) to zero. The media player is returned from a fast forward state to the paused state. In some embodiments, as the contact intensity falls below the corresponding release intensity threshold for the higher playback speed, the reduction of the playback speed to zero may be gradual (e.g., in accordance with the rate of reduction of the contact intensity).

Although the above description of FIGS. 6A and 6B uses fast forwarding as an example. The same control heuristic can be used for rewinding. For example, in response to a light press input detected on a rewind control (e.g., rewind control 514) while the media player is in a paused or stopped state, the rewind speed is increased from zero to a first rewind speed (e.g., 2×) in the backward direction when the intensity of the press input reaches above the activation intensity threshold associated with the first rewind speed (e.g., 2×). Depending on the intensity profile of the press input relative to the lock time threshold T_(L), the rewind speed may be locked in at the first rewind speed (e.g., 2×), or returned to zero when the intensity of the press input drops below the release intensity associated with the first rewind speed (e.g., 2×).

In some embodiments, the respective activation intensity threshold and release intensity threshold associated with the first fast forward speed (e.g., 2×) are the same. In some embodiments, the respective activation intensity threshold and release intensity threshold associated with the first fast forward speed (e.g., 2×) are different, with the activation intensity threshold being greater than the release intensity threshold. In some embodiments, the activation intensity threshold and release intensity threshold associated with the first higher speed level (e.g., fast forward speed of 2× and rewind speed of 2×) are the same as the activation intensity threshold and release intensity threshold for a tap input that activates the play button (e.g., play control 510) of the media player.

FIG. 6A above illustrates how to lock into a next higher playback speed with a light press input while the media player is in a stopped or paused state. FIGS. 6B-6D illustrate control heuristics in which higher playback speeds (e.g., different levels of fast forward or rewind speeds) are not locked in at the end of the press input (e.g., a press input with an intensity reaching above one or more higher activation intensity thresholds (e.g., the activation intensity thresholds associated with 2×, 5×, and 10× speeds). Instead, the playback speed is gradually stepped up in discrete levels and then stepped down to a predetermined level (e.g., 0×).

FIG. 6C illustrates that, when the media player is at a paused or stopped state (with a playback speed of 0×), a deep press input with an intensity reaching above the respective activation intensity thresholds associated with two consecutive fast forward speeds (e.g., I_(2×A) associated with fast forward speed 2×, and I_(5×A) associated with fast forward speed 5×) is detected. In response to the rising intensity of the deep press input, the playback speed is stepped up from zero (0×) to the first fast forward speed (e.g., 2×) upon the intensity crossing the activation intensity threshold (e.g., I_(2×A)) associated with the first fast forward speed (e.g., 2×). Then, as the intensity of the deep press input continues to increase and crosses the activation intensity threshold (e.g., I_(5×A)) associated with the next higher fast forward speed (e.g., 5×), the playback speed is stepped up from the first fast forward speed (e.g., 2×) to the next higher fast forward speed (e.g., 5×). When the intensity of the deep press input then decreases and crosses the release intensity threshold (e.g., I_(5×R)) associated with the highest achieved fast forward speed (e.g., 5×), the playback speed is stepped down from the highest achieved fast forward speed (e.g., 5×) to the next lower fast forward speed (e.g., 2×). When the intensity of the deep press input further decreases and crosses the release intensity threshold (e.g., I_(2>R)=I_(LR)) associated with the next lower fast forward speed (e.g., 2×), the media player is returned to the paused state with a playback speed of zero (0×).

FIG. 6D is similar to FIG. 6C, where the media player is in a stopped or paused state when a deep press input is detected. The intensity of the deep press input reaches above the respective activation intensity thresholds associated with three fast forward speeds (e.g., I_(2×A) associated with fast forward speed 2×, I_(5×A) associated with fast forward speed 5×, and I_(10×A) associated with fast forward speed 10×). In response to the rising intensity of the deep press input, the playback speed is stepped up from zero to the initial fast forward speed of 2× upon the intensity crossing the activation intensity threshold I_(2×A), then from the initial fast forward speed of 2× to the next higher fast forward speed of 5× upon the intensity crossing the activation intensity threshold I_(5×A), and then from the fast forward speed of 5× to the next higher fast forward speed of 10× upon the intensity crossing the activation intensity threshold I_(10×A). When the intensity of the deep press input has peaked and started to decrease, the playback speed is stepped down from the highest achieved fast forward speed of 10× to the next lower fast forward speed of 5× upon the intensity crossing the release intensity threshold I_(10×R) associated with the fast forward speed of 10×. When the intensity of the deep press input decreases further and crosses the release intensity threshold I_(5×R) associated with the fast forward speed of 5×, the playback speed is stepped down from the fast forward speed of 5× to the next lower fast forward speed of 2×. When the intensity of the press input decreases further and crosses the release intensity threshold I_(2×R) (e.g., I_(2×R)=I_(LR)) associated with the fast forward speed of 2×, the media player is returned to the paused state with a playback speed of zero.

Although the above description of FIGS. 6C and 6D uses fast forwarding as an example. The same control heuristic can be used for rewinding. For example, in response to a deep press input detected on a rewind control (e.g., rewind control 514) while the media player is in a paused or stopped state, the rewind speed is stepped up from zero to two or more higher rewind speeds (e.g., 2×, 5×, and 10×) in the backward direction when the intensity of the deep press input reaches above the activation intensity threshold associated each of those higher rewind speeds. On the down-stroke of the deep press input, the rewind speed is stepped down from the highest achieved rewind speed to each of the lower rewind speeds, and finally to zero, when the intensity of the deep press input reaches below the release intensity threshold associated with each of the previously achieved rewind speeds.

FIGS. 6E and 6F illustrate how a lock time threshold T_(L) (e.g., the same T_(L) value or a different T_(L) value from the T_(L) value in FIGS. 6A and 6B) is used to determine whether a light press input that triggers activation of a first fast forward speed (e.g., 2×) will cause the fast forward speed to be locked in after the light press input is terminated. In FIGS. 6E and 6F, the initial playback speed at the time that the light press input is received is the normal playback speed (e.g., 1×). In other words, the media content is in a normal playback state when the light press input is first detected (e.g., with a finger-down event triggered by the initial contact of a finger on the touch screen). The lock time threshold T_(L) may be any suitable length (e.g., 50 ms, 100 ms, 200 ms, 300 ms, 500 ms, 700 ms, or 1000 ms), and is optionally predefined in accordance with user preference or heuristics.

FIG. 6E illustrates an exemplary scenario where the intensity of the deep press input increases above the activation intensity threshold I_(2×A) (e.g., I_(2×A)=the activation intensity threshold I_(LA)-for a “light press” input) of a first fast forward speed (e.g., 2×), and then falls below the release intensity threshold I_(2×R) (e.g., I_(2×R)=the activation intensity threshold I_(LR)-for a “light press” input) of the first fast forward speed (e.g., 2×) before the lock time threshold T_(L) expires. The intensity of the light press never reaches the next higher activation intensity threshold (e.g., I_(5×A)). As a result, the speed of playback is increased from the normal playback speed (e.g., 1×) to the first fast forward speed (e.g., 2×) upon crossing of the activation intensity threshold I_(2×A) and remains at the first fast forward speed (e.g., 2×) after the intensity of the light press input has dropped below the release intensity threshold I_(2×R) for the first fast forward speed (e.g., 2×) and the press input is finally terminated (e.g., when the intensity drops below the contact-detection intensity or becomes undetectable).

FIG. 6F illustrates an exemplary scenario where, instead of falling below the release intensity threshold I_(2×R) before the lock time threshold T_(L) is reached, the intensity of the light press input stayed above the release intensity threshold I_(2×R) until the lock time threshold T_(L) has expired. The intensity of the press input then falls below the release intensity threshold I_(2×R) of the first fast forward speed (e.g., 2×) before the press input is terminated. The intensity of the light press input never reached the next higher activation intensity threshold (e.g., I_(5×A)). As a result, the speed of playback is increased from the normal playback speed (e.g., 1×) to the first fast forward speed (e.g., 2×) upon crossing of the activation intensity threshold I_(2×A) and remains at the first fast forward speed (e.g., 2×) until the intensity of the light press input drops below the release intensity threshold I_(2×R) for the first fast forward speed (e.g., 2×). When the intensity of the light press input drops below the release intensity threshold I_(2×R) for the first fast forward speed (e.g., 2×), the playback speed is decreased from the first fast forward speed (e.g., 2×) to the normal playback speed (e.g., 1×). The media player is returned from a fast forward state to the normal playback state.

Although the above description of FIGS. 6E and 6F uses fast forwarding as an example. The same control heuristic can be used for rewinding. For example, in response to a light press input detected on a rewind control (e.g., rewind control 514) while the media player is in a normal playback state (e.g., at 1× speed), the media player can change the normal playback speed in the forward direction to a first rewind speed (e.g., 2×) in the backward direction when the intensity of the light press input reaches above the activation intensity threshold associated with the first rewind speed (e.g., 2×). Depending on the intensity profile of the light press input relative to the lock time threshold T_(L), the rewind speed may be locked in at the first rewind speed (e.g., 2×) in the backward direction, or returned to the normal playback speed (e.g., 1×) in the forward direction when the intensity of the light press input drops below the release intensity associated with the first rewind speed (e.g., 2×).

FIG. 6E above illustrates how to lock into a next higher playback speed with a light press input while the media player is in a normal playback state. FIGS. 6F-6H illustrate control heuristics in which higher playback speeds (e.g., different levels of fast forward or rewind speeds) are not locked in at the end of the press input (e.g., a deep press input with an intensity reaching above one or more higher activation intensity thresholds (e.g., the activation intensity thresholds associated with 2×, 5×, and 10× speeds). Instead, the playback speed is gradually stepped up in discrete levels and then stepped down to a predetermined level (e.g., 1×).

FIG. 6G illustrates that, when the media player is already in a normal playback state (e.g., with a playback speed of 1×), a deep press input reaching above the respective activation intensity thresholds associated with two consecutive fast forward speeds (e.g., I_(2×A) associated with fast forward speed 2×, and I_(5×A) associated with fast forward speed 5×) is detected. In response to the rising intensity of the press input, the playback speed is stepped up from the normal playback speed (e.g., 1×) to the first fast forward speed (e.g., 2×) upon the intensity crossing the activation intensity threshold (e.g., I_(2×A)) associated with the first fast forward speed (e.g., 2×). Then, as the intensity of the deep press input continues to increase and crosses the next higher activation intensity threshold (e.g., I_(5×A)) associated with the next higher fast forward speed (e.g., 5×), the playback speed is stepped up from the first fast forward speed (e.g., 2×) to the next higher fast forward speed (e.g., 5×). When the intensity of the deep press input then decreases and crosses the release intensity threshold I_(5×R) associated with the highest achieved fast forward speed (e.g., 5×), the playback speed is stepped down from the highest achieved fast forward speed (e.g., 5×) to the next lower fast forward speed (e.g., 2×). When the intensity of the deep press input further decreases and crosses the release intensity threshold (e.g., I_(2×R)=I_(LR)) associated with the lowest fast forward speed (e.g., 2×), the media player is returned to the normal playback state with a normal playback speed (e.g., 1×).

FIG. 6H is similar to FIG. 6G, where the media player is already in a normal playback state (e.g., with a playback speed of 1×) when a deep press input is detected. The intensity of the deep press input reaches above the respective activation intensity thresholds associated with three fast forward speeds (e.g., I_(2×A) associated with fast forward speed 2×, I_(5×A) associated with fast forward speed 5×, and I_(10×A) associated with fast forward speed 10×). In response to the rising intensity of the deep press input, the playback speed is stepped up from the normal playback speed (e.g., 1×) to the initial fast forward speed (e.g., 2×) upon the intensity crossing the lowest activation intensity threshold (e.g., I_(2×A)), then from the initial fast forward speed (e.g., 2×) to the next higher fast forward speed (e.g., 5×) upon the intensity crossing the corresponding activation intensity threshold (e.g., I_(5×A)), and then from that higher fast forward speed (e.g., 5×) to the next, even higher fast forward speed (e.g., 10×) upon the intensity crossing the corresponding activation intensity threshold (e.g., I_(10×A)). When the intensity of the deep press input has peaked and started to decrease, the playback speed is stepped down from the highest achieved fast forward speed (e.g.,10×) to the next lower fast forward speed (e.g., 5×) upon the intensity crossing the release intensity threshold (e.g., I_(10×R)) associated with the highest achieved fast forward speed (e.g., 10×). When the intensity of the deep press input decreases further and crosses the release intensity threshold (e.g., I_(5×R)) associated with the fast forward speed of 5×, the playback speed is stepped down from the fast forward speed of 5× to the next lower fast forward speed of 2×. When the intensity of the press input decreases further and crosses the release intensity threshold I_(2×R) (e.g., I_(2×R)=I_(LR)) associated with the fast forward speed of 2×, the media player is returned to the normal playback state and stays in the normal playback state with a playback speed of 1×. Corresponding user interface changes for the scenario shown in FIG. 6H are illustrated in FIGS. 5A-5F.

Although the above description of FIGS. 6G and 6H uses fast forwarding as an example. The same control heuristic can be used for rewinding. For example, in response to a deep press input detected on a rewind control (e.g., rewind control 514) while the media player is in a normal playback state, the device goes from the normal playback state into the rewind state, and the rewind speed is stepped up from zero to two or more higher rewind speeds (e.g., 2×, 5×, and 10×) in the backward direction when the intensity of the deep press input reaches above the activation intensity threshold associated each of those higher rewind speeds. On the down-stroke of the deep press input, the rewind speed is stepped down from the highest achieved rewind speed to each of the lower rewind speeds, and finally to zero, when the intensity of the deep press input reaches below the release intensity threshold associated with each of the previously achieved rewind speeds. When the rewind speed is back to zero, the device restarts the playback with a normal playback speed in the forward direction.

FIGS. 6I-6K illustrate three control heuristics in which the initial playback speed of the media content is greater than the normal playback speed, e.g., at a first fast forward speed of 2×, when a press input is detected.

FIG. 6I illustrates a control heuristic in which the lock time threshold T_(L) is not used to lock in a higher playback speed (e.g., a fast forward speed of 5×). As shown in FIG. 6I, the initial playback speed at the time that the press input is received is the first fast forward speed (e.g., 2×). In other words, the media content is already being fast forwarded at 2× speed after a previous press input (e.g., the press input described in FIGS. 6A or 6E) on the fast forward control has been processed. As shown in FIG. 6I, in some embodiments, instead of triggering the next higher fast forward speed (e.g., 5×) upon detecting the intensity of the press input reaching above the activation intensity threshold (e.g., I_(5×A)) associated with the next higher fast forward speed (e.g., 5×), the playback speed is increased from the current fast forward speed (e.g., 2×) to the next higher fast forward speed (e.g., 5×) when the intensity of the light press input drops below the release intensity threshold I_(LR) of a light press. In other words, instead of triggering the activation of the higher playback speed on the down-stroke (or pushing down) of the light press input, the higher playback speed is triggered on the up-stroke (or lifting up) of the light press input. As shown in FIG. 6I, if the media player is already in a fast forward state, a newly detected tap input on the fast forward control will cause the media player to go into and lock in the next higher fast forward speed (e.g., 5×).

Although the above description of FIGS. 6I uses fast forwarding as an example. The same control heuristic can be used for rewinding. For example, when the media player is already in the rewind state with a rewind speed of 2× in the backward direction, in response to a tap input detected on the rewind control (e.g., rewind control 514), the media player changes the rewind speed from 2× to 5× and maintains it at 5× in response to the intensity of the tap input falling below the release intensity threshold I_(LR).

FIG. 6J illustrates that, when the media player is already in an initial fast forward state (with a fast forward speed of 2×), a deep press input reaching above the respective activation intensity threshold associated with the next higher fast forward speed (e.g., I_(5×A) associated with fast forward speed of 5×) is detected. In response to the rising intensity of the deep press input, the playback speed is stepped up from the initial fast forward speed of 2× to the next higher fast forward speed of 5× upon the intensity crossing the activation intensity threshold I_(5×A) associated with the next higher fast forward speed of 5×. When the intensity of the deep press input then decreases and crosses the release intensity threshold I_(5×R) associated with the fast forward speed of 5×, the playback speed is stepped down from the fast forward speed of 5× to the next lower fast forward speed of 2×. When the intensity of the deep press input further decreases and crosses the release intensity threshold I_(2×R) (e.g., I_(2×R)=I_(LR) ) associated with the fast forward speed of 2×, the media player is returned to the normal playback state with a normal playback speed of 1×.

It is worth noting that in FIGS. 6I and 6J, if the media player is already in a fast forward state (e.g., with a playback speed of 2×), a press input may trigger the next higher fast forward speed (e.g., 5×) either on the up-stroke (e.g. lifting up) or the down-stroke (e.g., pushing down) of the press input. Specifically, if the press input is a light press that only crosses the lowest activation intensity threshold (e.g., I_(LA)), the next higher fast forward speed (e.g., 5×) is triggered when the intensity of the press input decreases and crosses the release intensity threshold (e.g., I_(LR) ) corresponding to the lowest activation intensity threshold (e.g., I_(LA)). In contrast, if the press input is a deep press that crosses not only the lowest activation intensity threshold (e.g., I_(LA)), but also one or more higher activation intensity thresholds (e.g., I_(5×A) , I_(10×A) , etc.), the next higher fast forward speed (e.g., 5×) is triggered when the intensity of the press input increases and crosses the next higher activation intensity threshold (e.g., I_(5×A) ).

FIG. 6K illustrates that, when the media player is already in an initial fast forward state (with a fast forward speed of 2×), a deep press input reaching above the respective activation intensity thresholds associated with two higher fast forward speeds (e.g., I_(5×A) associated with fast forward speed 5× and I_(10×A) associated with fast forward speed 10×) is detected. In response to the rising intensity of the deep press input, the playback speed is stepped up from the initial fast forward speed of 2× to the next higher fast forward speed of 5× upon the intensity crossing the activation intensity threshold I_(5×A) associated with the next higher fast forward speed of 5×. Then, in response to further rising of the intensity of the deep press input, the playback speed is stepped up from the fast forward speed of 5× to the next higher fast forward speed of 10× upon the intensity crossing the activation intensity threshold I_(10×A) associated with the next higher fast forward speed of 10×. When the intensity of the deep press input then decreases and crosses the release intensity threshold I_(10×R) associated with the fast forward speed of 10×, the playback speed is stepped down from the fast forward speed of 10× to the next lower fast forward speed of 5×. When the intensity of the deep press input decreases further and crosses the release intensity threshold I_(5×R) associated with the fast forward speed of 5×, the playback speed is stepped down from the fast forward speed of 5× to the next lower fast forward speed of 2×. When the intensity of the press input decreases further and crosses the release intensity threshold I_(2×R) (e.g., I_(2×R)=I_(LR) ) associated with the fast forward speed of 2×, the media player is returned to the normal playback state with a normal playback speed of 1×.

Although only three levels of fast forward speeds are shown in FIGS. 6D, 6H, and 6K, additional higher levels of fast forward speeds (e.g., 20×, 30×, 60×, 100×, 500×, etc.) are possible, each having an increasingly higher activation intensity threshold and corresponding release intensity threshold.

Similarly, although FIGS. 6I-6K shows the initial playback speed to be the lowest fast forward speed, the same heuristics shown in these figures are optionally used in cases where the initial playback speed is higher than the lowest fast forward speed. For example, if the initial playback speed at the time when the press input is detected is 5×, the playback speed can be stepped up to 10× on the up-stroke (or lifting up) of a light press input when the intensity crosses the release intensity threshold I_(LR) . If the media player supports additional levels of playback speeds above 10× (e.g., 20×, 50×, 100×, etc.) and if the initial playback speed is 10×, each of these higher playback speeds (e.g., 20×, 50×, 100×) may be achieved one by one with the intensity of a deep press input crossing respective activation intensity thresholds associated with the different higher playback speeds (e.g., 20×, 50×, 100×). In some embodiments, the activation and release intensity thresholds of the higher playback speeds may be adjusted (e.g., lowered) depending on the initial playback speed of the media content.

Although the above description of FIGS. 6I-6K uses fast forwarding as an example. The same control heuristic can be used for rewinding. In response to a light press input detected on the rewind control (e.g., rewind control 514), the media player can step up the rewind speed from an initial value (e.g., 2×) in the backward direction to the next higher rewind speed (e.g., 5×) upon lift up of the light press input. In response to a deep press input detected on the rewind control, the media player can step up the rewind speed from the initial value (e.g., 2×) in the backward direction to one or more higher rewind speeds (e.g., 5×, and/or 10×) in response to the contact intensity crossing the corresponding activation intensity thresholds of the one or more higher rewind speeds. The media player can then step down the rewind speeds one level at a time when the contact intensity of the press input crosses the release intensity threshold of each of the one or more achieved rewind speeds. In the case of rewinding, when the contact intensity of the deep press input crosses the lowest release intensity threshold (e.g., I_(2×R)=I_(LR) ) corresponding to the lowest rewind speed (e.g., 2×), the playback speed is optionally changed from the lowest rewind speed (e.g., 2×) in the backward direction to the normal playback speed (e.g., 1×) in the forward direction.

Although FIGS. 6A-6K shows the changes in playback speeds in discrete steps that are integer multiples of the normal playback speed (e.g., 1×), in some embodiments, the change from one level to the next may be implemented as a gradual change that goes through multiple sub-steps (e.g., as factions speeds 1.2, 1.5, 1.7, 1.9, etc.) or a curved slope in a predetermined transition period (e.g., 2 ms). In some embodiments, the mapping of the multiple sub-steps to the intensity values of the contact is triggered when a modification input (e.g., holding down an “option” key) is detected concurrently with detecting the interaction with the media playback control.

In various embodiments, a subset or all of the above control heuristics may be implemented in a particular media player application to control media presentation.

FIGS. 7A-7H illustrate a flow diagram of a method 700 of controlling media presentation in accordance with some embodiments. The method 700 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 700 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, the method 700 provides an intuitive way to control playback speed of a media presentation. The method reduces the cognitive burden on a user when changing media playback speed in software applications, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to control media playback faster and more efficiently conserves power and increases the time between battery charges.

While presenting media content (e.g., a collection of images in a slideshow, an audio track, a video, or the like) at a first non-zero playback speed, the device detects (702) a press input by a first contact on the touch-sensitive surface that corresponds to a focus selector at a first location of a first media control on the display (e.g., a fast-forward control). For example, the first playback speed is 1× speed (e.g., FIGS. 6E-6H). In another example, the first playback speed is ≥2× where the user previously performed one or more legacy tap/click operations at the first location that corresponds to the first media control to present the media item at the first playback speed (e.g., FIGS. 6I-6K).

In response to detecting the press input: the device determines (704) whether an intensity of the first contact (e.g., a characteristic intensity) is above a first intensity threshold. In some embodiments, the first intensity threshold corresponds to a predetermined minimum playback speed such as 2×, 5×, or 10× . For example, the user must at least press hard enough to get above the 2× threshold before the playback speed is changed based on intensity. In some embodiments, the intensity of the first contact passes through a plurality of intensities that correspond to intensity thresholds for playback speeds below the current playback speed.

In accordance with a determination that the intensity of the first contact is above the first intensity threshold, the device presents the media content at a second playback speed, where the second playback speed is faster than the first non-zero playback speed. In some embodiments, the first intensity threshold is distinct from a detection threshold or an activation intensity threshold, which are lower than the first intensity threshold (e.g., the first intensity threshold is higher than the activation intensity threshold).

In accordance with a determination that the intensity of the first contact is below the first intensity threshold, the device maintains presentation of the media content at the first non-zero playback speed.

In some embodiments, a contact having an intensity above the activation intensity threshold on the touch-sensitive surface at a location that corresponds to another user interface element besides the first media control initiates an operation that corresponds to the another user interface element. For example, a contact having an intensity above the activation intensity threshold on the touch-sensitive surface at a location that corresponds to a play button initiates provision of the media content at a normal playback speed (e.g., 1×).

In some embodiments, the first non-zero playback speed is (706) a normal playback speed (e.g., FIGS. 6E-6H). In some embodiments, the media content is presented at the default speed in which the media content was captured/generated when played in the normal playback speed (i.e., 1×).

In some embodiments, the first non-zero playback speed is (708) a fast-forward playback speed that is greater than or equal to two times a normal playback speed (e.g., FIGS. 6I-6K). In some embodiments, the first non-zero playback speed is (710) a rewind playback speed whose magnitude is greater than or equal to two times a normal playback speed. (e.g., 2×, 5×, etc.).

In some embodiments, the first intensity threshold corresponds (712) to a predetermined minimum intensity value. For example, the user must press at least hard enough to get above the intensity threshold that corresponds to the 2×, 5×, or 10× playback speed before the playback speed is changed based on intensity.

In some embodiments, the first playback control corresponds (714) to a fast-forward control (e.g., 512).

In some embodiments, the first playback control corresponds (716) to a rewind control (e.g., 514).

In some embodiments, the media content includes (718) a collection of one or more images, an audio track, and/or a video.

In some embodiments, while presenting the media content at the second playback speed, the device detects (720) a subsequent press input by a second contact distinct from the first contact (e.g., after the first contact by a first finger ends/lifts off, a second contact by the same first finger is detected as part of a second press input) on the touch-sensitive surface that corresponds to the focus selector at the first location of the first media control on the display. In response to detecting the subsequent press input, the device determines whether an intensity of the second contact has crossed a second intensity threshold that is above the first intensity threshold. In some embodiments, the intensity of the second contact is deemed to have crossed above the second intensity threshold based on a determination that the intensity of the second contact has changed from below the second intensity threshold to above the second intensity threshold. In some embodiments, while detecting the subsequent press input and before detecting the intensity of the second contact increase above the second intensity threshold, the device detects the intensity of the second contact increase above the first intensity threshold without providing tactile output corresponding to crossing the first intensity threshold. While continuing to detect the second contact on the touch-sensitive surface, and in accordance with a determination that the intensity of the second contact has crossed above the second intensity threshold: the device provides tactile output that corresponds to the second intensity threshold, and presents the media content at a third playback speed greater than the second playback speed. In accordance with a determination that the intensity of the second contact has not crossed above the second intensity threshold, the device foregoes provision of the tactile output that corresponds to the second intensity threshold and continues to present the media content at the second playback speed. In some embodiments, detents are provided upon crossing intensity thresholds that are greater than the one that corresponds to the current playback speed (e.g., the second playback speed) but not when crossing the intensity threshold that corresponds to the current playback speed or any lower speeds. In some embodiments, visual feedback is also provided as the intensity thresholds are crossed that are greater than the threshold that corresponds to the current playback speed.

In some embodiments, in response to detecting the press input: the device, in accordance with the determination that the intensity of the first contact is above the first intensity threshold, provides (722) tactile output that corresponds to the first intensity threshold; and in accordance with the determination that the intensity of the first contact is below the first intensity threshold, the device foregoes provision of the tactile output that corresponds to the first intensity threshold. In some embodiments, detents are provided upon crossing intensity thresholds that are greater than the one that corresponds to the current playback speed (e.g., the first non-zero playback speed) but not when crossing the intensity threshold that corresponds to the current playback speed or any lower speeds. In some embodiments, visual feedback is also provided as the intensity thresholds are crossed that are greater than the one that corresponds to the current playback speed.

In some embodiments, while presenting the media content at the second playback speed, the device detects (724) a subsequent press input by a second contact distinct from the first contact (e.g., after the first contact by a first finger ends/lifts off, a second contact by the same first finger is detected as part of a second press input) on the touch-sensitive surface that corresponds to the focus selector at the first location of the first media control on the display. While detecting the subsequent press input, the device detects that an intensity of the second contact has crossed above the first intensity threshold. In response to detecting that the intensity of the second contact has crossed above the first intensity threshold: in accordance with a determination that the first intensity threshold is above a predetermined minimum intensity value (e.g., the predetermined minimum intensity value corresponds to a minimum playback speed for providing tactile output such as 2×, 5×, or 10×), the device provides tactile output that corresponds to the first intensity threshold; and, in accordance with a determination that the first intensity threshold is below the predetermined minimum intensity value, the device foregoes provision of the tactile output that corresponds to the first intensity threshold.

While continuing to detect the second contact on the touch-sensitive surface, the device detects (726) that the intensity of the second contact has crossed above a second intensity threshold that is above the first intensity threshold. In response to detecting that the intensity of the second contact has crossed above the second intensity threshold: in accordance with a determination that the second intensity threshold equals or exceeds the predetermined minimum intensity value, the device provides tactile output that corresponds to the second intensity threshold; and, in accordance with a determination that the second intensity threshold does not equal or exceed the predetermined minimum intensity value, the device foregoes provision of the tactile output that corresponds to the second intensity threshold. For example, detents are provided upon reaching intensity thresholds above and including the predetermined minimum intensity value for a predefined playback speed such as 2×, 5, or 10×. In some embodiments, the predetermined minimum intensity value must be reached before the playback speed is changed based on intensity. In some embodiments, visual feedback is also provided as the intensity increases above the predetermined minimum intensity value.

In some embodiments, in response to detecting the press input, and in accordance with the determination that the intensity of the first contact is above the first intensity threshold: in accordance with a determination that the first intensity threshold is above a predetermined minimum intensity value (e.g., the predetermined minimum intensity value corresponds to a minimum playback speed for providing tactile output such as 2×, 5×, or 10×), the device provides (728) tactile output that corresponds to the first intensity threshold; and, in accordance with a determination that the first intensity threshold is below the predetermined minimum intensity value, the device foregoes provision of the tactile output that corresponds to the first intensity threshold. For example, detents are provided upon reaching intensity thresholds above and including the predetermined minimum intensity value for a predefined playback speed such as 2×, 5×, or 10× . In some embodiments, the predetermined minimum intensity value must be reached before the playback speed is changed based on intensity. In some embodiments, visual feedback is also provided as the intensity increases above the predetermined minimum intensity value.

In some embodiments, while presenting the media content at the second playback speed, and while continuing to detect the first contact on the touch-sensitive surface: the device detects (730) that the intensity of the first contact is above a second intensity threshold distinct from the first intensity threshold. In some embodiments, the second intensity threshold has a pressure or force threshold higher than a pressure or force threshold in the first intensity threshold. In response to detecting that the intensity of the first contact is above the second intensity threshold, the device presents the media content at a third playback speed, where the third playback speed is faster than the second playback speed. In some embodiments, the playback speeds include 0×, 1×, 2×, 5×, 10×, 30×, and 60×. For example, the first playback speed is 1×, the second playback speed is 10×, and the third playback speed is 30×.

In some embodiments, while presenting the media content at the third playback speed, and while continuing to detect the first contact on the touch-sensitive surface, the device detects (732) that the intensity of the first contact has crossed below the second intensity threshold. In response to detecting that the intensity of the first contact has crossed below the second intensity threshold: the device provides tactile output that corresponds to the second intensity threshold and presents the media content at the second playback speed. In some embodiments, the intensity of the first contact is deemed to have crossed below the second intensity threshold based on a determination that the intensity of the first contact has changed from being above the second intensity threshold to being below the second intensity threshold. While presenting the media content at the second playback speed, and while continuing to detect the first contact on the touch-sensitive surface, the device detects that the intensity of the first contact has crossed below the first intensity threshold. In response to detecting that the intensity of the first contact has crossed below the first intensity threshold: the device provides tactile output that corresponds to the first intensity threshold and presents the media content at a fourth playback speed. For example, the playback speed is reduced and detents are provided as the intensity crosses below each intensity threshold.

In some embodiments, while presenting the media content at the second playback speed, the device detects (734) a subsequent press input by a second contact distinct from the first contact (e.g., after the first contact by a first finger ends/lifts off, a second contact by the same first finger is detected as part of a second press input) on the touch-sensitive surface that corresponds to the focus selector at the first location of the first media control on the display. While detecting the subsequent press input: the device determines whether an intensity of the second contact has not crossed above a second intensity threshold that is above the first intensity threshold; and, subsequent to a determination that the intensity of the second contact has not crossed above the second intensity threshold: the device detects that the intensity of the second contact has crossed below the first intensity threshold; and, in response to detecting that the intensity of the second contact has crossed below the first intensity threshold, the device foregoes provision of a tactile output that corresponds to the first intensity threshold.

In some embodiments, while presenting the media content at the second playback speed, and while continuing to detect the first contact on the touch-sensitive surface, the device detects (736) that the intensity of the first contact is below the first intensity threshold. In one example, lift-off of the first contact is detected. In another example, the intensity of the first contact falls below first intensity threshold but lift-off is not detected. In response to detecting that the intensity of the first contact is below the first intensity threshold, the device presents the media content at a fourth playback speed.

In some embodiments, the fourth playback speed is (738) the second playback speed. For example, provision of the media content at the second playback speed is maintained. In some embodiments, actuation of a modifier key is required to lock in a higher playback speed.

In some embodiments, the fourth playback speed is (740) the first non-zero playback speed. For example, the playback speed is reduced from the second playback speed. In some embodiments, the playback speed tracks the intensity of the contact, so that as the intensity of the contact decreases from an intensity above the first intensity threshold to an intensity below the first intensity threshold, the playback speed is adjusted through a plurality of levels that are mapped to different contact intensities.

In some embodiments, the fourth playback speed is (742) a normal playback speed. In some embodiments, the media content is presented at the default speed in which that the media content was captured/generated when played in the normal playback speed (i.e., 1×). In some embodiments, in the fourth playback speed (e.g., 0×), a still image that corresponds to the media content is presented. For example, in the 0× playback speed, the media content is paused.

In some embodiments, while presenting a still image that corresponds to the media content, (i.e., 0× playback speed), the device detects (744) a subsequent press input by a second contact distinct from the first contact (e.g., after the first contact by a first finger ends/lifts off, a second contact by the same first finger is detected as part of a second press input) on the touch-sensitive surface that corresponds to the focus selector at the first location of the first media control on the display. In some embodiments, the media content is paused when played in the 0× playback speed. In some embodiments, provision of the media content is paused in response to a user activation (e.g., using a touch input) of a pause button in the user interface. In response to detecting the subsequent press input: the device determines whether an intensity of the second contact (e.g., a characteristic intensity) is above the first intensity threshold. In accordance with a determination that the intensity of the second contact (e.g., characteristic intensity) is above the first intensity threshold, the device presents the media content at the second playback speed. In accordance with a determination that the intensity of the second contact is below the first intensity threshold, the device increases the playback speed of the media content from the still image up to the second playback speed according to the intensity of the second contact. For example, the fast-forward control operates like a gas pedal whereby the playback speed increases from 0× to 2× before the intensity of the second contact crosses the first intensity threshold. Alternatively, in some embodiments, the electronic device maintains presentation of the still image corresponding to the media content until the intensity of the second contact crosses the first intensity threshold (e.g., a jump from 0× to 2×).

In some embodiments, while presenting the media content at a normal playback speed (e.g., 1×), the device detects (746) a subsequent press input by a second contact distinct from the first contact (e.g., after the first contact by a first finger ends/lifts off, a second contact by the same first finger is detected as part of a second press input) on the touch-sensitive surface that corresponds to the focus selector at a second location of a second media control (e.g., the play control) on the display, wherein the second playback control is distinct from the first playback control. The device determines whether the intensity of the second contact (e.g., characteristic intensity) is above the first intensity threshold. In accordance with a determination that the intensity of the second contact is above the first intensity threshold, the device presents the media content at a first fractional playback speed, wherein the first fractional playback speed is faster than the normal playback speed and less than two times the normal playback speed. In accordance with a determination that the intensity of the second contact is below the first intensity threshold, the device maintains presentation of the media content at the normal playback speed. In some embodiments, the fractional playback speeds include 1.1×, 1.2×, 1.5×, and 1.7×. Alternatively, in some embodiments, the fractional playback speeds are accessed in response to detecting a press input at a location corresponding to the first playback control in addition to detecting activation of a modifier key (e.g., the option key).

In some embodiments, while continuing to detect the second contact on the touch-sensitive surface: the device detects (748) that the intensity of the second contact is above a second intensity threshold distinct from the first intensity threshold. In response to detecting that the intensity of the second contact is above the second intensity threshold, the device presents the media content at a second fractional playback speed, wherein the second fractional playback speed is faster than the first fractional playback speed and less than two times the normal playback speed.

In some embodiments, in response to detecting the subsequent press input, the device displays (750) a fractional playback scrubber at least partially overlaid on the second playback control that indicates a current playback speed of the media content. In some embodiments, the fractional playback scrubber is adjacent to but not overlaid on the second playback control. In some embodiments, detents are provided when crossing above all intensity thresholds over a predetermined minimum intensity value. In some embodiments, detents are provided when crossing below all intensity thresholds.

In some embodiments, the second playback control corresponds (752) to at least one of: a play control and a pause control.

It should be understood that the particular order in which the operations in FIGS. 7A-7H have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., method 800) are also applicable in an analogous manner to method 700 described above with respect to FIGS. 7A-7H. For example, the contacts, gestures, press input, user interface objects, tactile outputs, intensity thresholds, focus selectors, and playback speeds described above with reference to method 700 optionally have one or more of the characteristics of the contacts, gestures, press input, user interface objects, tactile outputs, intensity thresholds, focus selectors, playback speeds described herein with reference to other methods described herein (e.g., method 800). For brevity, these details are not repeated here.

FIGS. 8A-8C illustrate a flow diagram of a method 800 of controlling media presentation in accordance with some embodiments. The method 800 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 800 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, the method 800 provides an intuitive way to control playback speed of media presentation. The method reduces the cognitive burden on a user when changing media playback speed in software applications, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to control media playback faster and more efficiently conserves power and increases the time between battery charges.

In some embodiments, while presenting media content (e.g., a collection of images in a slideshow, an audio track, a video, or the like) at a first speed, the device detects (802) a press input by a first contact on the touch-sensitive surface that corresponds to a focus selector at a first location of a first media control on the display (e.g., a fast-forward control). In some embodiments, the first speed is not a fast-forward speed. For example, the first speed is 0× speed (e.g., paused) or 1× speed (e.g., normal playback).

In response to detecting the press input by the first contact: the device determines (804) whether a first intensity of the first contact (e.g., a characteristic intensity) has satisfied a first intensity threshold (e.g., an activation intensity threshold). In some embodiments, the first intensity threshold is an activation intensity threshold for a first intensity stage. Subsequent to determining whether the first intensity of the first contact has satisfied the first intensity threshold (e.g., an activation intensity threshold), the device determines whether the first contact continues to satisfy a second intensity threshold (e.g., remaining above a release intensity threshold) during a predefined time interval (e.g., before a lock time threshold is reached). In some embodiments, the second intensity threshold is a release intensity threshold for the first intensity stage.

In accordance with determining that the first intensity of the first contact has satisfied the first intensity threshold and determining that the first contact continues to satisfy the second intensity threshold during the predefined time interval, the device presents the media content at a first fast-forward speed that is higher than the first speed as long as the first contact satisfies the second intensity threshold (e.g., as shown in FIGS. 6B and 6F, where the higher speed is not locked in at the end of the press input).

In accordance with determining that the intensity of the first contact has satisfied the first intensity threshold and determining that the first contact does not continue to satisfy the second intensity threshold during the predefined time interval (e.g., the first contact is lifted off or the intensity of the first contact falls below the second intensity threshold during the predefined time interval), the device presents the media content at the first fast-forward speed (e.g., even though the first contact is no longer detected on the touch-sensitive surface) (e.g., as shown in FIGS. 6A and 6E, where the higher speed is locked in).

In some embodiments, the first intensity threshold is (806) higher than the second intensity threshold (e.g., the activation intensity threshold for the first fast forward speed may be higher than the release intensity threshold for the first fast forward speed). In some embodiments, the first intensity threshold is identical to the second intensity threshold.

In some embodiments, while presenting the media content at the first fast-forward speed (e.g., 2×) in accordance with determining that the first intensity of the first contact has satisfied the first intensity threshold and determining that the first contact continues to satisfy the second intensity threshold during the predefined time interval, the device detects (808) a second intensity of the first contact that does not satisfy the second intensity threshold subsequent to the predefined time interval (e.g., as shown in FIG. 6B and 6F, where the intensity of the press input falls below the release intensity threshold for 2× after the lock time threshold has expired). In response to detecting the second intensity of the first contact that does not satisfy the second intensity threshold subsequent to the predefined time interval, the device ceases to present the media content at the first fast-forward speed (e.g., as shown in FIG. 6B and 6F, where the playback speed is returned to the initial playback speed when the contact intensity crosses the release intensity threshold associated with the first fast forward speed of 2×). In some embodiments, ceasing to present the media content at the first fast-forward speed includes presenting the media content at the first speed. In some embodiments, ceasing to present the media content at the first fast-forward speed includes presenting the media content at a normal playback speed (e.g., as shown in FIG. 6F where the final speed is 1×). In some embodiments, ceasing to present the media content at the first fast-forward speed includes presenting a still image of the media content (e.g., paused state and/or 0× speed) (e.g., as shown in FIG. 6B where the final speed is 0×).

In some embodiments, while presenting the media content at the first fast-forward speed (e.g., 2×) in accordance with determining that the first intensity of the first contact has satisfied the first intensity threshold and determining that the first contact does not continue to satisfy the second intensity threshold during the predefined time interval, the device detects (810) a press input by a second contact on the touch-sensitive surface that corresponds to the focus selector at the first location of the first media control on the display. In some embodiments, the second contact is distinct and separate from the first contact. The device determines whether a first intensity of the second contact (e.g., a characteristic intensity) has satisfied the first intensity threshold (e.g., an activation intensity threshold). Subsequent to determining whether the first intensity of the second contact has satisfied the first intensity threshold (e.g., an activation intensity threshold), the device determines whether the second contact satisfies the second intensity threshold (e.g., remaining above a release intensity threshold). In accordance with determining that the first intensity of the second contact has satisfied the first intensity threshold (e.g., I_(LA)) and subsequently determining that the second contact does not satisfy the second intensity threshold (e.g., I_(LR) ), the device presents the media content at a second fast-forward speed (e.g., 5×) that is higher than the first fast-forward speed (e.g., 2×). This is illustrated in FIG. 6I, for example, after the intensity of the press input has risen above I_(LA), reached a peak, and then fallen to a point just below I_(LR) , the playback speed is increased to 5×.

In some embodiments, in response to detecting the press input by the second contact, in accordance with determining that the first intensity of the second contact has satisfied the first intensity threshold (e.g., I_(LA)) and subsequently determining that the second contact satisfies the second intensity threshold (e.g., I_(LR) ), the device presents (812) the media content at the first fast-forward speed while the second contact satisfies the second intensity threshold. This is illustrated in FIG. 6I, for example, where, after the intensity of the press input has risen above I_(LA), and remains above I_(LR) , the playback speed remains at 2×, and does not increase to 5× until the intensity falls to a point below I_(LR) .

In some embodiments, in response to detecting the press input by the second contact, in accordance with determining that the first intensity of the second contact has satisfied the first intensity threshold and subsequently determining that the second contact satisfies the second intensity threshold, the device visually distinguishes (814) the first media control on the display while the second contact satisfies the second intensity threshold. In some embodiments, the visual distinction indicates that the second contact satisfies the second intensity threshold. For example, in FIG. 6I, during the period of time after the intensity of the press input has risen above I_(LA), reached a peak, and then fallen to a point just above I_(LR) , the playback speed remains at 2×, but the media control being activated by the press input is optionally highlighted to indicate that the activation intensity threshold for the next higher play speed has been achieved, and that ceasing the press input now would cause an increase in the playback speed and subsequent locking in of the increased playback speed.

In some embodiments, while presenting the media content at the first fast-forward speed (e.g., 2×) in accordance with determining that the first intensity of the first contact has satisfied the first intensity threshold and determining that the first contact continues to satisfy the second intensity threshold during the predefined time interval and while continuing to detect the first contact on the touch-sensitive surface, the device detects (816) a second intensity of the first contact that satisfies a third intensity threshold (e.g., I_(5×A)) that is higher than the first intensity threshold (e.g., I_(2×A)). In some embodiments, the third intensity threshold is an activation intensity threshold for the second intensity stage (e.g., 5×). In response to detecting the second intensity of the first contact, the device presents the media content at the second fast-forward speed (e.g., 5×) that is higher than the first fast-forward speed (e.g., 2×). This is illustrated in FIG. 6J, where a deep press meeting I_(5×A) causes the playback speed to increase from 2× to 5×.

In some embodiments, while presenting the media content at the second fast-forward speed (e.g., 5×) and while continuing to detect the first contact on the touch-sensitive surface, the device detects (818) a third intensity of the first contact that does not satisfy a fourth intensity threshold (e.g., I_(5×R)). In some embodiments, the fourth intensity threshold is a release intensity threshold for the second intensity stage. In some embodiments, the fourth intensity threshold is identical to the third intensity threshold. In some embodiments, the fourth intensity threshold is distinct from the third intensity threshold. In response to detecting the third intensity of the first contact, the device presents the media content at the first fast-forward speed. This is illustrated in FIG. 6J, where after the intensity of the deep press input falls below the release intensity threshold I_(5×R) , the previously achieved higher playback speed 5× is reduced to 2× again.

Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

As shown in FIG. 10, an electronic device 1000 includes a display unit 1002 configured to display a user interface, a touch-sensitive surface unit 1004 configured to receive contacts, one or more sensor units 1006 configured to detect intensity of contacts with the touch-sensitive surface unit 1004; and a processing unit 1010 coupled with the display unit 1002, the touch-sensitive surface unit 1004 and the one or more sensor units 1006. In some embodiments, the processing unit 1010 includes: a detecting unit 1012, a determining unit 1014, a presenting unit 1016, a ceasing unit 1018, and a distinguishing unit 1020.

Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.
